The concept of the smart ring, focused primarily on health and well-being, has been around for several years, but it remains a relatively niche market. However, major tech brands such as Samsung and Apple could soon take up this technological challenge and add smart rings to their product ranges.

Until now, the smart ring market has been fairly limited in options, with brands such as the Finnish specialist start-up, Oura, focusing mainly on activity tracking – both day and night. But the market could get shaken up by the arrival of major manufacturers, starting with the world's number one smartphone seller, Samsung.
